To all whom t may concern:

Be it known that I, RALPH HAYs DANNER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State nof California, have invented certain new and useful Improvements in Rotary Pumps, of which the following is a specification.

This invention relates to improvements in rotary pumps, and it is an object of the invention to provide a pump in which a propolling member is provided -for driving or lifting the-water, and a deiecti-ng member is emfployed for straightening the column' of water and preventing its beingwhirled within the pu-mp barrel without advancement therein.

It is also anobject of the invention to provide a pumping 'mechanism in which one or more pumping units are employed and properly connected. the unit or units used having propelling and defiecting portions for driving and directing water. l

It is a still further object of the invention to provide a pumping mechanism having a rotary propeller, and a. centering spider arranged within the barrel of the pump, for holding the propeller so that it cannot engage the pump barrel though closely fitting within the same.

It is also a further object of the invention to provide a pumping mechanism with a series voili' pump units, said units being connected aand driven by a hollow shaft, whereby the bearings of the pump parts may be lubricated from within :said shaft without the danger yof grit or foreign substances reaching the bearings and cutting or .destroying the same.

ln the accompanying drawing, forming part of this speciticationfr'l Figure 1 is a vertical, central, sectional view taken through a pump constructed in accordance with the present invention, intermediate portions of' the .pump barrel or casing -being broken away. Fig. 2 is a central, sectional view of a pump unit constructed in accordance with this invention, the same being shown upon an enlarged scale. Fig. 3 is a detail, transverse, sectional view taken upon the line 3--3 .of d? i '2. Fig. l is a sectional view taken longitudinally through one of the puanp units. and showing -the 'same when employed without .a `central pest (ir-shaft. Fig. ..5 is :a transverse, sectional view taken upcn .a3- .oflilig 4.. is acentral.,

longitudinal, sectional view taken, through one of the pump units, the propeller and defiector being shown in elevation, and screw studs being illustrated for holding, the said detiector in position. Fig. 7 is a transverse, sectional view taken upqn the line 7--7 of Fig. 6. l The pumping mechanism forming the subject matter of the present invention is especially well adapted for use in bored wells, though of course it may be employed 1n other places where it is desired to lift or transfer water, oil or other liquids. The pump has been illustrated as it is unually constructed when employed in alwell bore, and the details and features of the invention will now be described, reference being had to the drawing. In the said drawing, 10 indicates a pump unit, 11 an intermediate casing and lil a framing for supporting said casing and pump unit. The pump units and casings are sor constructed that one or more pump units may be employed with any desired intermediate length of casing between, in accordance with the depth of the well, and the amount of propelling force desired in raisinga column of Water. Thus, as shown in Fig. 1, a plurality ofvpurnp units maybe used with interconnecting casing-sections 11. The upper casing section 11 is screwed in to the lower end of frame 12 and thus supports all the pumping mechanism below.

Each of the pumping units l0 comprises a barrel `13 having therein a defiecting member 14, and a propeller 15. The deflector 14 is made in the form of a-spider having a hollow hub portion 16, and radiating deiiectors 17. `The deflectors, usually about four in number, extend radially from the hub portion and are adapted `to closely engage the barrel 13 so as to exactly spacefthe said deiiector and the propeller below it, within the said barrel 13.. ln order to prevent the deflecting member from turnin in the barrel 13, the outer edges et the de ectors 17 engage grooves 18 formed longitudinally in the inner surfaces of the said barrel 13. The delecting-fmember le, thus itted in position, forms arigid support vfori 4bricated from the interior of the hollow section 20, which extends through the said deflecting member.

Immediately below vthe 'delecting member 14 is the ropeller 15, which is provided with a hollbw hub portion 21, and one or more spirally arranged ights 22. The lower ends ofthe de ectors 17 are usually somewhat reduced in width and extend downwardly to a pointnear the upper end of flights 22. These projections 23 are pref# erably curved, as shown in Fig. 46, so as to tend to guide the liquids lifted by the propeller towardl the straight portions of the deflectors, the edect of all of the deflectors being to straighten the column of'- l1qu1d and give it a vertical direction after it has been. acted upon by .the propeller. The upper and lower endsof the hub 16 are provided with annular grooves 24 and 25, in .which packing 26 may be placed. Coo eratingzwith the said grooves, are grooves and 2.8, formed in the upper end of the .shaft section 20, and the upper `end of the propeller hub 2l respectively. These grooves also receive the packing 26, so that aV liquid tight joint is formed between the deflecting member and the parts immediately above and below the hub thereof. The inner surface of bushing 19 is preferably grooved at .38 to facilitate the spreading of a lubricant upon the bearing surface thereof. Oil or other lubricant is admitted to vthe inner face of said bushing by means of diagonal bores 29 formed in the upper part of the shaft section 20. The lubricant is also-lead from the said bushing back into the interior of the shaft section by similar bores 30 formed in the lower end of said shaft section. The bearing within `the de iicting member may thus be properly lushafting employed in operating the propellers, and the packing 26 prevents the escape of the oil or other lubricant from the shafting, and also positively excludes any sand, grit or other material which may pass through the. well casing and the barrels 13 during the pumping operation. The upper end of the hollow shaft section 20 employed in the uppermost pumping unit is screwed upon `the vend of a hollow shaft section 31, which in turn is connected with a hollow driving shaft 32, having an actuatin pulley 33 secured tothe upper end thereo The saidhollow shaft 32 finds suitable bearings inthe frame 12. Ball bearings at 34 and 35 are. provided for holding said shaft section 32 movably in position, and supporting ball bearings 36, of any' desired type are also employed for supporting' the pulley 33, and the hollow shafting used in the pump. An oil well 3f?l is usually provided for inclosing 'the ball bearings 34 and 36, and lubricant may be supplied thereto through piping 39 afmanfoilucilp 40 mountedthereon. .,LAnvoil.

well 41 is also arranged about the ball bearing 35 and around the upper end of the hollow shaft 32. Oil or other lubricant placed within said oil well 41 may be caused to run into the upper open end of the hollow shaft 32, and pass thence downwardly through all of the hollow shaft sections mounted within the pump casing. The moving parts of the pump may thus be continually supplied with a proper lubricant from the interior of the shaft sections, and in such a manner as not to be interfered with by the liquids pumped or propelled through the pump casings and barrels.

The pumpmechanism of this invention may be used with a hollow shafting alone as above described, or may also be employed with a central stiffening post or shaft 45. Such a post 45 is illustrated in Figs. 1, 2 and 3 of the drawing, and extends centrally through all of the hollow shaft sections of the pump mechanism. The upper end of the said shaft is supported by acrosshead46 extending across the oil well 41. The upper end of said shaft 45 is usually bored at 47, and carries an oil cup 48, through which lubricant may be introduced into said bore 47. Branch bores 49 lead the oil into the interior of the hollow shaft 32. Oil or other lubricant may thus be supplied to the hollow shafting and caused to overflow into the oil well 4l for thoroughly lubricating all of the working parts. The shaft 45 engages bearings within the propellers 15, the said propellers being provided with suitable bushings 50 when the post 45 is employed. The bushings may be grooved upon their inner faces at 51, to 'facilitate the proper spreading of the lubricant upon the surface thereof, and also to facilitate the passage of lubricant to the shaft sections and propellers below the same. The lower end of the lowermost propeller is usually provided with a stuffing box 52 which closely fits upon the lower end of the post 45, and thus prevents the oil or other lubricant from escaping from the shaft sections. Thepo 45 projects below the stuffing box 52 and engages a spider or crosshead 53 at the lower end of the lowest casing section 11. The said crosshead is open around the said post 45, to permit liquids to be drawninto the pump casings and barrels. The post 45 thus adds further rigidity and stiffness to the parts and offers bearings for the various propellers employed. The central post 45 is not necessary however to the oper tion of the pump and in many' instances the pump is employed without such a post. When so employed, the lower end of the lower propeller 15 is closed by means of a cap 54, as clearly shown in Fig. 4 of the drawing. The said propeller'l is also'n'ot provided with any interior bushing orf-bear- .ingsurface when the post-is not employed.

f members,

As shown in Figs. 6 and 7, the deilecting instead of engaging grooves formed in the barrels of the pumping units, may engage, and be held in place by a series of set screws 55, which are mounted in the walls of the unit barrel; Each of said set screws is provided with an inner projecting end having a notch 56 formed therein adapted to receive the edge of' one of the dellectors 17'.` The said screws form an effective means for properly spacing the deecting member within' the barrel of the pump unit, and also permits of its adjust" ment vertically, so as to take its proper position between the propeller below it, and the shaft section upon which it is journaled.

lt will be evident that other' minor changes in the details of construction may be made without departing from the spirit of the invention.

It will be observed that each of the said pumping units may be inserted or taken from the pumping mechanism as a whole, since each of said units embraces a barrel 13, a deflecting member 14, which forms a central bearing carrying spider within the barrel, a propeller arranged immediately below the defiector and the shaft section,

which supports and turns the propeller, and A which isl journaled within the said deflecting member. The barrel of each pumping unit is connected with the barrel of an adjacent pumping unit, by means of any desired length of pump casing' il, andthe hollow shaft section, as .well as the hub `of the propeller is connected by other hollow shaft sections with the actuating shafting driven by the pulley 33. The pump casing or4 barrel portion may Y thus be lengthened or shorteped to suit the depth of the well in which the pump is located,

and any desired number of pump units with their liquid raising propellers may be arranged-within they mechanism, all within the spirit and scope of the present invention.

The etliciency of the propellers, with their spirally arranged flights, is greatly increased by the employment y of deiectors adjacent thereto. The said deilectors straighten the column of water and guide it in the desired direction, preventing its merely whirling spirallyfwithin the casing as would be the' effect if the propellers without such guiding deflectors were employed.

In operation, the pulley 33 is driven by prope'allers for sti any suitable means, for turning the hol low shafting and rotating the propellers. The said propellers vlift the water or other liquid, any twisting action given thereto, being rectied by the deiiectors as the column of Water advances in the pump barrel. The liquids find an outlet through the discharge opening 58.

What is claimed is:

l. A pump mechanism comprising a series of pump units, and pump casings connecting the same, hollow shafting extending through said units and casings, spiders carried by the units and having bearings therein for said shafting, the shafting sections which engage said spiders having lubricant guiding bores in their Walls, and propellers mounted in each of said units and connected with said shafting, whereby the said propellers may be rotated Within the Casing, and driving means for the said shafting.

2. A pump mechanism comprisingapump casing having pump units forming portions thereof, deflecting spiders mounted in Said pump units and having bearings therein, propellers mounted in the said pump units and having hollow hubs, hollow shafting sections connected with said hollow hubs,

,some of said shaft sections engaging the bearings in said spiders and havmg perforated lubricant transmitting walls, means for rotating said shafting and means :for directing lubricants into said hollow shafting, whereby the bearings of the pump will lbe fed interiorly with lubricants.

for driving said propellers and a central post extending through the pump mecha nism .and engaging the bearings within the ening and centering the same, the bearings within the propeller having lubricant guiding bores communicating with adjacent hollow shafting.

In testimony whereof, I have hereunto set my hand, in the presence of two witmesses.l A
